I've open-sourced the study app I built to memorise the TCM meridian system. The domain is niche but the engineering choices might interest this sub:

• Provenance as a type system — every content string carries source IDs into a typed registry plus a review status; unsourced fields honestly render as unsourced instead of being filled in.
• Ethics enforced by CI — a test fails if symptom terms enter the search index (that would make it a treatment recommender) or if needling instructions enter the data. The safety rules aren't a README section; they're red tests.
• A coordinate engine built on bone-cun, the classical proportional unit — every point placed from a named landmark + parsed distance, with an audit script that demands zero drift across all 362 points.
• Local-first PWA: no accounts, no telemetry, works offline. React + Vite + a lot of hand-drawn SVG.

It's educational only (no diagnosis, no prescriptions, no efficacy claims), bilingual 繁體中文/English, and looking for two kinds of contributors: developers, and TCM teachers/practitioners willing to put their name on data review.

Hello community,

I created a website to follow each countries effort to reach net zero in 2050. The data vizualisation lets you compare different countries' emission over the years and whether they are on the right path to reach their goal.

View every country and find more information on: https://lucabron.github.io/netzero/index.html

Open-Meteo hands you all 40 ICON members, so I had a go at plotting the

fan rather than the median line.

Spread over London was 0.6°C at hour zero and 5.4°C by day 5. Knew that

in principle, hadn't actually looked at it before.

Couple of things I'm unsure about. I've drawn a marker where the 80%

band goes past 5°C as a rough "past here it's a range not a number",

but 5 is arbitrary — would normalising against climatology for the

location and season be more defensible? And I've noted that spread

underestimates actual error, but I don't have a feel for by how much.

Hello! I want to track a bunch of things (ie, mood, sleep, temperature) over time, and be able to superimpose them to look for correlations and patterns (which would involve some shenanigans on the Y-axis, I know). Is there a good free/cheap program with which I could do that? Is this even the right subreddit to ask? Bonus points for no AI, bonus points if it can actually do analysis.

Hello, I have been trying to build perfect graph interface for 3 years now, non of the ones I used are really useful, just looks cool. I would really appreciate if you guys can share your thoughts. Can even graph be usefull? I came to conclusion that it can be achieved through consistent smart(automatic) grouping, and showing user what might be useful for him depending on user’s query, and ability to let user explore. What is your perfect graph vision?

Hi everyone! 👋
I’m a Computer Science student at the University of Houston working on an independent UX/product design project about accessibility and navigation.
I’m researching how people with different accessibility needs navigate unfamiliar places and what information would make that experience easier, safer, and less frustrating.
I’m looking for people who would be willing to have a 20–30 minute casual interview about their experiences.
I’d love to learn about things like:
• How you plan a trip to an unfamiliar place
• What accessibility information you look for beforehand
• Problems you've experienced with maps/navigation apps
• How you deal with inaccessible routes, entrances, elevators, sidewalks, etc.
• What information you wish navigation apps provided
• What would make you feel more confident before starting a trip
There are no right or wrong answers. I’m interested in your experiences and opinions, not medical information. You can skip any question you don't want to answer.
This is for a student UX portfolio project, and I’m not selling anything or promoting a product.
If you're comfortable participating, please comment or send me a DM. I really appreciate anyone willing to share their experience. ❤️
